Steve Nash is a great shooter, one of the best in the league. He certainly belongs on that list... he's just so much more than a pure shooter, that he doesn't get the credit for it. But you can't leave him open with the ball anywhere on the floor.
In case you don't know ( I'm sure you don't ) who Andrew Toney was, he was the shooting guard for the Sixers when they won the championship in the early 80s. Averaged 20 ppg on 53% shooting. Unfortunately got injured and his career was over after 4-5 years.
